[Mesa-users] Custom color file

[Aaron Dotter]

Hi Susmita,

It's difficult to answer your question since you didn't state what MESA
version you're using.  However, I can tell you that the MIST bolometric
correction tables include multiple "sub-tables" with different values of
the extinction (Av).  So all of the Teff, log(g) values will be repeated
many times (one for each value of Av).  That may or may not be the reason
for the error you have received.  If it is, then you should restrict
yourself, presumably, to the first sub-table in the file, which has Av = 0.
